Secret Agent No. 6 Demo - Update V.0.2.9
Hey all, it was some time ago! To compensate for the longer development time, I decided to add the second mission to the demo as well: Bridge. (At this rate, the whole game will eventually be in the demo.) Note that aspects of the demo missions might still change as development goes on. An example is the music. In the meantime, I can confidently say that most of the non-horror missions are finished. This means that there has been some good progress in the last couple of months, and I'd like to share some other small changes. Some changes include the following: Slightly higher movement speed Inverted look/aim options Aim sensitivity can now be changed Enemy corpse removal disabled (can be enabled via options) The grading system is a little more forgiving Enemies are slightly weaker for all difficulties Some bug fixes I thank you all for your patience. If you are interested in some 'behind the scenes', I do post from time to time here. Have fun!Read full article on Community Announcements (Bytehyve)Patch NotesOfficial
Secret Agent No. 6 Demo - Update V.0.2.8
Happy Steam Next Fest (and almost Halloween)! I've made some big steps behind the scenes for the full game. While little has effect on the demo, I thought it is still worth posting. This includes some bug fixes, tweaks, and optimization. Some other changes include the following: Snappier and less disorienting leaning Updated AI behavior Large AI pathfinding optimization Slightly increased melee damage Some other optimizations Some texture tweaks Some effect tweaks Some minor bug fixes Again, thank you for any feedback. It is always welcome. If you are interested in some 'behind the scenes', I do post from time to time here. Have fun!Read full article on Community Announcements (Bytehyve)Patch NotesOfficial
Secret Agent No. 6 Demo - Update V.0.2.7
Hello everybody! I hope you are doing good. Due to a lower pace in development than expected, I have decided to add an extra mission to the demo to compensate for the longer wait time. This update to 0.2.7 brings some changes, tweaks, optimization, and the third mission of the game. Mission 2.2. Port: The third mission has you cross a heavily guarded cargo port to infiltrate a leaving ship. It is a follow-up of the second mission, which is not playable in the demo. However, you might get a small sneak peak. Although the mission is as good as complete, it will get its unique soundtrack later. Should you run into any problems with this mission, be sure to let me know. For now, enjoy! Some other changes include the following: New unique reticles per weapon type Some extra UI animations Some weapon and recoil tweaks Some AI difficulty tweaks (mostly to make the starting difficulties slightly easier) Some texture tweaks Some graphic tweaks (which give a cleaner look, and might improve performance) Better AI pathfinding (which should also improve performance) Large pickup hitboxes Some minor bug fixes I want to thank everybody who has given feedback as it helps me out immensely. If you face any problems or have more suggestions, let me know. Have fun!Read full article on Community Announcements (Bytehyve)AnnouncementsOfficial
Secret Agent No. 6 - Development status (+ devlog)
Hi everybody! The development of Secret Agent No. 6 has been lacking due to some busy school and work periods. As I want to bring out a great product, more time will be needed. This means that the current release date has been pushed back for some time (unclear how far exactly). To make up for the longer wait time, I have started a devlog where I'll be showcasing some of the 'behind the scenes' into making Secret Agent No. 6. Should you be interested, you view the devlog here. If you don't want to miss out on any updates, subscribing can be done through the Official page. Furthermore, I have decided to soon add a second level (not including the tutorial) to the demo to give you guys more gameplay beforehand. Although it won't contain any of the horror that is eventually present in the full game, it can be fun exploring for now. Stay tuned for this! Should you have any questions or run into problems with the demo, do not hesitate to let me know. Have fun!Read full article on Community Announcements (Bytehyve)Patch NotesOfficial
Secret Agent No. 6 Demo - Minor Update V.0.2.5
Hi everybody! Development on the game goes well and I've made a lot of progress. While working on the full game, I'll try to keep the demo up to date with the latest relevant developments. I've noticed some small bugs related to the AI which should be fixed with this update. Also, the AI is more prone to distractions, making the rock a viable choice for your loadout. Some of the other changes for this update are as follows: Some AI behavior tweaks Some minor hitbox tweaks Some minor equipment tweaks Some minor texture tweaks Ragdoll is more satisfying Replaying the tutorial allows you to instantly dive into the firing range If you are facing any problems, or have suggestions, let me know!
